Because interests are shown up to two deci- mal places, licensee holdings in a field may add up to less than 100 per cent. Interests are shown at 1 January 2003. Recoverable reserves originally present refers to reserves in resource categories 0, 1, 2 and 3 in the NPD’s classification system (see the definitions below). Recoverable reserves remaining refers to reserves in resource categories 1, 2 and 3 in the NPD’s classification system (see the definitions below). Resource category 0: Petroleum sold and delivered Resource category 1: Reserves in production Resource category 2: Reserves with an approved plan for development and operation Resource category 3: Reserves which the licensees have decided to develop Explanation of the figures Oil: 1 000 b/d Gas: bn scm/year NGL: mill tonnes/year Condensate: mill scm/year FIELDS IN PRODUCTION 69 2˚ 4˚ 6˚ 169 59˚ 59˚ 204 189 25 242 STAVANGERSTAVANGER 15/3-1 S Gudrun Statpipe eepipe II A eepipe 15/3-4 Z Z 25 265 265 Glitne 48 29 15/5-2 ipe II B 243 48 eep 15/5-1 Dagny Z 29 15/919 S Volve Sleipner 16/7-2 12 West 46 46 Sleipner East 15/8-1 72 Alpha Gungne 241 Sigyn 38 38 Varg 15/12-12 18/10-1 58˚ 58˚ Eu Eu r opip r opipe II e I Yme 271 7/7-2 148 240 Mime 18 Ula 019 Cod 57˚ 57˚ Tambar 1/3-6 1/2-1 143 Gyda 19 2/2-5 19 274 239 18 2/4-17 Tjalve 2/4-10 239 146 Tor Albuskjell 1/5-2 Flyndre West Ekofisk Ekofisk 2/5-3 South-East Tor 18 66 44 Edda Eldfisk Tommeliten Gamma 3/7-4 Trym 147 2/7-19 Embla 2/7-29 6 18 Valhall 273 Awarded acreage Fra 2/12-1 Freja Hod npipe 113 Norpip Norpipe e 56˚ 56˚ 2˚ 4˚ Southern North Sea sector The southern part of Norway’s North Sea sector became important for the country at an early stage, with Ekofisk as the first Norwegian offshore field to come on stream more than 30 years ago. Ekofisk serves as a hub for petroleum operations in this area, with surrounding developments utilising the infrastructure which ties it to continental Europe and Britain. Norwegian oil and gas is exported from Ekofisk to Teesside in the UK and Emden in Germany respectively. Although production from this part of the NCS has lasted for many years, remaining resources in the region are substantial. Oil and gas output is accordingly expected to continue beyond anoth- er three decades. 70 FIELDS IN PRODUCTION Oil: 1 000 b/d Gas: bn scm/year 500 16 14 400 12 300 10 8 200 6 100 4 2 0 0 1971 1974 1977 1980 1983 1986 1989 1992 1995 1998 2001 12 Ekofisk area (incl Ekofisk, Eldfisk, Embla and Tor) Ekofisk, Eldfisk and Embla Blocks and Blocks 2/4 and 2/7 - production licence 018. production licences Both blocks awarded in 1965.

In addition come Albuskjell, Cod, Edda and West Ekofisk, which have ceased production. This area has been developed in five phases. Ekofisk and its central processing facilities were developed in two stages, with production starting in 1971. Cod and West Ekofisk represented phase three. Oil was initial- ly loaded into tankers on the fields, but has been piped since 1975 through the Norpipe line to Teesside in the UK. Pipeline transport of gas through Norpipe to Emden in Germany began in 1977. Approved by the authorities in 1975, the fourth development phase covered Albuskjell, Eldfisk and Edda. The last of these came on stream in 1979. The fifth phase was prompted by a desire to improve recovery from Ekofisk, and the 2/4-K water injection platform began operation in December 1987. Expanded several times, water injection capacity on the field is currently just under one mill b/d. The Edda platform was modified in 1988 to receive gas from the Tommeliten field. A decision to develop the Embla field south of Ekofisk was taken in 1990, with production starting in 1993. A new plan for development and operation of the Ekofisk field (Ekofisk II) received approval in 1994, when the licence for the Ekofisk area was extended to 2028. A new Ekofisk field centre comprising two platforms has been installed on the field. The 2/4-X wellhead platform was put in place during the autumn of 1996, fol- lowed by the 2/4-J processing and transport installation in August 1997. Ekofisk II came.
